I am trying build ctags from sources, but get following error:

Build output in start, says what i have pkg-config with 0.29.2, but error says pkg-config not installed or version less then 0.18... I am not understand what going wrong. Trying check configure.ac file for more information, but without result...

How i can fix this?

where is your pkg.m4 file located?

unrealslayer commented 10 months ago

where is your pkg.m4 file located?

/usr/share/aclocal/pkg.m4 (root:root) (-rw-r--r--)

leleliu008 commented 10 months ago

It seems that the pkg-config command is found, but pkg.m4 is not found, you could fix this via:

export ACLOCAL_PATH=/usr/share/aclocal

export ACLOCAL_PATH=/usr/share/aclocal

Thank you! Build fixed! Do you know why i must explicit set ACLOCAL_PATH var?

leleliu008 commented 10 months ago

I'm not sure the exact reason, but https://www.gnu.org/software/automake/manual/html_node/Macro-Search-Path.html may help you to understand.

leleliu008 commented 10 months ago

Oh, I see, I found your aclocal path is /usr/local/bin/aclocal, so the default macro search path sould be /usr/local/share/aclocal, but actually your pkg.m4 is located in /usr/share/aclocal which in turn is not the default macro search path. that's why you should explicitly set ACLOCAL_PATH

your pkg-config command path is /usr/bin/pkg-config, it shouldn't be /usr/local/bin/pkg-config?

leleliu008 commented 10 months ago

The most obvious reason is that you installed pkg-config via apt, but other packages were installed via other package manager or manully built and --prefix=/usr/local option was used.

Its true, automake, autoconf was builded from sources, but pkg-config is not... I am did not know what it can give me so strange errors, thank you again! I will try build pkg-config from sources too and hope what aclocal variable no longer needed explicit set!
